Definitions

  • the present invention relates to a device for on-board diagnosis, in particular for a motor vehicle system, which has a plurality of functional components which are networked with one another and at least two of which are control units. Furthermore, the present invention relates to a corresponding method for on-board diagnosis of a system. Such on-board diagnosis can be carried out in motor vehicles, track-guided vehicles, ships, aircraft and the like. The general term “vehicle” is used for this below.
  • the fault diagnosis of control units and the components controlled thereby, in particular of a motor vehicle is usually carried out by means of self-diagnosis by the control unit itself. This means that the diagnosis is only limited to the control unit with the respective controlled components. If an error is determined by the self-diagnosis, an error message is stored in the control unit. The error message is then called up in a workshop with the help of a workshop tester. Since the self-diagnosis only affects one control unit or its controlled components, no faults that span components or systems can be detected. However, since more and more control devices are installed in motor vehicles, which may be networked with one another, it is increasingly important to be able to carry out a fault diagnosis in these networked systems.
  • control devices and controlled components usually come from different manufacturers, and therefore different implementations or interpretations of specifications can take place.
  • a cross-system diagnostic method is known from German published patent application DE 100 51 781 A1.
  • the diagnosis takes place in two Stages, namely a component diagnosis and a central system diagnosis, whereby a component and a state assigned to the system size are output by the component diagnosis as a result to the central system diagnosis.
  • So-called model data of the components and the system are stored in a function matrix.
  • the linking of the states of the system variables with functional states and the determination of faulty functions is carried out with the help of a function matrix tensor.
  • the disadvantage here is that the very extensive function matrix, which would have to take into account all the functional relationships of the individual components, must be stored in a corresponding diagnostic device.
  • the object of the present invention is therefore to propose a simplified on-board diagnostic method and a corresponding simplified on-board diagnostic device.
  • this object is achieved by a device for on-board diagnosis of a vehicle system, in particular a motor vehicle system, which has a plurality of functional components which are networked with one another, at least two of which are control devices, with a computing device which has a connection device with the plurality of functional devices Components can be connected, for recording and evaluating component data of the multiple components, the computing device having a mathematical model with which functional relationships of the multiple components can optionally be calculated, including the connecting device, so that errors and / or errors relating to the components can be calculated from the component data Connection device can be determined in a targeted manner in the vehicle.
  • the invention provides a method for on-board diagnosis of a vehicle system, in particular a motor vehicle system, which has a plurality of functional components which are networked with one another, by recording and evaluating component data of the plurality of components, a mathematical model being used to evaluate the component data is used to optionally calculate the functional relationships of the several components, including a connection device for networking the components, so that from the component data errors and / or errors spanning components regarding the connection device can be determined in a targeted manner in the vehicle.
  • the model-based fault diagnosis has the advantage that no excessively large databases have to be stored in individual diagnosis or control devices.
  • model-based method can also detect so-called unknown causes of errors. These are causes of errors that are not covered by the known error codes. These causes of errors can be determined using the function dependencies stored in the model. Defective components can be inferred, for example, from the intersection of several error symptoms or interdependencies.
  • the on-board diagnostic device performs the comprehensive error diagnosis for all components, including the connection device, centrally.
  • all component or cross-system errors or error causes can be identified.
  • the model-based error diagnosis can also be used to identify multiple errors that are caused by several individual errors and are not easily ascertainable by a user.
  • the model-based, central diagnosis can also process or prevent so-called message showers, which are caused by a single error and, for example, affect several control units and cause a corresponding number of error messages.
  • the component data of the multiple components include unprocessed status data with regard to error diagnosis.
  • the component data include pre-processed status data and / or error data with regard to the fault diagnosis, with self-diagnoses or preliminary stages of self-diagnoses already being carried out in the individual components.
  • the on-board diagnostic device can also have a functional device for performing vehicle functions. It thus represents a unit that provides both functional and diagnostic direction is. This means that diagnostics can also be carried out across components or systems using a functional unit.
  • a vehicle system preferably consists of a plurality of functional components which are networked with one another and at least one model-based diagnostic device. If several of the components, including the connection device, each have a diagnostic unit, one or more of these components can perform a diagnostic master function in order to manage or evaluate diagnostic data from other components or their own diagnostic data. The data obtained through this diagnostic master function can be sent to a further system diagnosis.
  • FIG. 1 shows a block diagram of a motor vehicle system according to a first embodiment of the present invention.
  • Figure 2 is a block diagram of a motor vehicle system according to a second embodiment of the present invention.
  • FIG. 1 shows a block circuit diagram of a simplified motor vehicle system.
  • the motor vehicle system comprises four function control devices 11, 12, 13 and 14 and a diagnostic control device 15.
  • the function control devices 11 and 12 are connected to the diagnostic control device 15 via a bus system II.
  • the function control units 13 and 14, on the other hand, are connected to the diagnosis control unit 15 via a bus system I.
  • the function control devices 11 to 14 each have a self-diagnosis function.
  • the error messages obtained by the self-diagnosis of the individual function control devices 11 to 14 are optionally delivered to the diagnostic control device 15 with further, stored process data via the respective bus system I, II.
  • a cross-system model for detecting system error candidates runs centrally in this specially provided control unit 15.
  • the conventional self-diagnosis set a cross-system, model-based diagnosis, so that a hierarchical diagnosis system is created.
  • process data are also sent from the function control units 11 to 14 to the diagnosis control unit 15.
  • the diagnostic control unit 15 can use the model to assess centrally which cause of the error the data is based on, or at least carry out an error limitation. For example, self-diagnosis of the engine control unit can determine that the engine is stuttering and an appropriate error message is issued. If the diagnostic control unit 15 also receives process data that the engine stuttering occurs simultaneously with the addition of gas, the joint processing of the error message and the process data then leads to the corresponding cause of the error in a much more targeted manner.
  • a so-called diagnostic machine is integrated in the diagnostic control unit 15. With the help of this diagnostic machine, which works on the principle of the "general diagnostic engine” according to de Kleer or further developments based on it and in which a vehicle-specific error diagnosis model is loaded, the error codes or symptoms are analyzed. Possible error candidates are determined.
  • the bus systems I and II can represent the usual on-board networks.
  • a separate diagnostic network can also be connected in the motor vehicle, so that the individual function control devices have both a connection to a conventional motor vehicle bus and a connection to a diagnosis bus.
  • These bus systems are also modeled in the diagnostic control unit 15, so that the respective bus errors can also be recognized.
  • FIG. 2 A motor vehicle system according to a second embodiment of the present invention is shown in FIG. 2.
  • the structure of the system essentially corresponds to that of the embodiment in FIG. 1.
  • the diagnostic control unit 25 is identical to the diagnostic control unit 15.
  • the function control devices 21 to 24 have a model-based self-diagnosis. This means that this system is hierarchically model-based.
  • component models for the own stored agnose, while in the diagnostic control unit 25 an error model is used for cross-system diagnosis.
  • model-based diagnosis runs in each control unit, with which the local errors in the control unit and in its periphery can be detected.
  • the results of the control unit diagnosis are also transmitted to the diagnosis control unit 25 via the respective bus system, and with the help of the cross-system, model-based diagnosis and possibly further internal or external data, eg. B. further symptom information, system error candidates determined.

Abstract

L'objectif de cette invention est d'améliorer le diagnostic de systèmes de véhicule pourvus de plusieurs composants fonctionnels en réseau. A cet effet, les données d'état individuelles des organes de commande (11, 12, 13, 14) sont surveillées dans un organe de commande de diagnostic central (15) au moyen d'un modèle mathématique. Chaque organe de commande peut être également équipé d'un autodiagnostic éventuellement basé sur un modèle. Grâce à l'évaluation des erreurs et/ou des causes d'erreurs au moyen d'un modèle, les organes de commande ne nécessitent pas de grandes banques de données pour le diagnostic des erreurs.
